The Traffic patch WHEEL: is progress - HORSE: is horse & carriage traffic. This is the oldest patch of the NYPD. In 1904, the difficulties facing the public were a maze of people, horses, bicycles and vehicles vying for space on the streets that were often unpaved, muddy or dusty. The great number of horses on the streets that year was evidenced by the Mounted Division having a major unit called the "Traffic Squad." As vehicles rapidly grew in popularity, their great numbers on the street caused traffic jams. The "Bicycle Squad" which had been formed as a branch of the Traffic Squad by Theodore Roosevelt in 1895 was also used to catch speeders exceeding the city limit of eight (8) mph
